MAINTENENCE--ELECTRICAL
-Using the highest resistance range of the
multimeter,
measure the resistance between the resistor lead and
chassis ground.
Any meter reading less than infinity
(00)
indicates a short, necessitating resistor
replace-
ment.
To check the coil:
The most accurate test for determining the condition
of the ignition coil is made by measuring arcing distance
with the Kawasaki
Electrotester.
Since a tester other than
the Kawasaki Electrotester may produce a different
arcing distance, the Kawasaki
Electrotester
is recom-
mended for reliable
results.
-Remove the ignition coil and the resistor.
-Connect the ignition coil with its resistor to the
Kawasaki Electrotester as shown in the figure.
Do
not forget to connect the resistor in series with the
ignition coil primary winding.

-Gradually slide the arcing distance ad justing knob from
left to right (small distance to large distance) carefully
checking the
arcing.
-Stop moving the knob at the point where the arcing
begins to fluctuate
,
and note the knob position in mm.

*1. Measure with the Kawasaki Electrotester.
2.
Check the resistor before the
measurement.
If the distance reading is less than the value shown
in the
table,
the ignition coil or spark plug caps are
defective. To determine which part is defective, measure
the arcing distance again with the spark plug caps re-
moved from the ignition coil. If the arcing distance is
subnormal as before, the trouble is with the ignition
coil itself.
If the arcing distance is now normal, the
trouble is with the spark plug
caps.
If an Electrotester is not available
,
the coil can be
checked for a broken or badly shorted winding with an
ohmmeter. However,
an ohmmeter cannot detect layer
shorts and shorts resulting from insulation breakdown
under high voltage.
To measure the primary winding resistance:
-Set the ohmmeter to the x 1 n range, and connect one
ohmmeter lead to the pink lead and the other to the
green, black, or blue lead from the ignition coils.
To measure the secondary winding resistance:
-Unscrew the spark plug caps from the spark plug leads.
-Set the ohmmeter to th
e
x 1 kn range, and connect
one ohmmete
r
lead to one of the spark plug leads and
the other ohmmeter lead to the remaining spark plug
lead
.

If
the coil does not produce an adequate spark
,
or
if either the primary or secondary winding does not
have the correct
resistance,
replace the ignition coil.
With the highest ohmmeter range, check for conti
-
nuity between each ignition coil pink lead
,
and one
spark plug lead and the coil core (two tests on each
coil
).
If there is any
reading,
the coil is shorted and
must be replaced.
Also
,
replace the ign ition coil if
either spark plug lead shows visible damage.
